SPECIFICATION forming part of Letters Patent No. 380,630,'dated April 3, 1888.

Application filed June 14, 1857. Serial No. 241.304. (No model.) Patented in Canada June 27, 1887, No. 27,072.

To aZZ whom it may concern; heater A projects an arm, A, terminating in Be it known that I, JAMES ALEXANDER a forked end, a; and to the extinguisher B is JAMIESON, of the city of Montreal, in the securedadownwardly-projectingbar, B, with 55 district of Montreal and Province of Quebec, turned-up end I), so arranged that the end I) Canada, have invented certain new and useful will normally rest in the fork a, and the ex- Improved Safety Appliances for Railway-Cars, tinguisher thus be kept in a vertical position (for which I have obtained a patent in Canada, and inactive, as will be now explained, so long dated June 27 1887 No. 27,072,) and Ido hereas nothing happens to the car. I by declare that the following is a full, clear, and The construction of the extinguisher is as IO exact description of the same. shown in Fig. 4, and now to be described.

My invention has reference to means for D is a bottle or vessel containing such an preventing the contents of a railway-car stove amount of acid as will, when mixed with the or heater from setting fire to the car in any alkaline solution with which Bis filled, gener- 65 accident, and provides means by which any ate the greatest amount of carbonic-acid gas.

The pipe may be either of metal,

K is the valve body or seat, L being the forming part of this specification, in whichhead of a weighted lever, L, carried on the 85 Figure 1 is a view of part of the inside of a spindle Z on one side of the valve.

Similar letters of reference indicate like as desired. parts. The operation of my invention is as follows:

It will be seen that unless otherwise supturning on its side or the heater being shifted ported the extinguisher will fall forward in a from its place from any cause, the turned-up direction transversely to the car. From the end I) is disengaged from the fork a, the extinguisher 13 tips over, thus causing the mouth of the bottle D to slide past the seat F, (the springs H H, which offer a yielding resistance, allowing it to do so,) and the acid therein contained is discharged into the alkaline solution contained in the body of B, thus affecting the chemical reaction and the generation of gas. Simultaneously with this movement the head L of the lever L will leave open the down-pipe I, through which and the pipe I the liquid and gas will be discharged onto the contents of the grate in the heater.

By the operation just described the live coals in the heater will be extinguished or reduced to a condition in which it will be impossible for them to set fire to the wood-work or fittings of the car, and this instantaneously I upon any unusual movement of the car or the stove.

curved, so as to allow it to slip more easily past the mouth of the bottle D.

The fire-extinguisher B may be detached from the wall of the car by withdrawing the pivot-pin connecting the arms 0' with the bracket 0, and then used as a portable fireextinguisher, operated by tipping it.

Having thus described my invention, I beg to state that what I claim is as follows:

1. The combination, with a car-heater, of a chemical fire extinguisher in which the acidchamber is kept closed by a swinging weighted lever holding a stopper up against its mouth, the said fire-extinguisher being secured to the wall of the car by arms pivoted to it at points outside its vertical axis, a support from the heater holding the extinguisher normally in a vertical position, a pipe connecting the fireextinguisher with the fire-chamber of heater, and a valve for automatically opening such connection by the tipping of the vessel, all as herein set forth, and for the purposes described.

2. In combination with a car-heater, a chemical fire-extinguisher constructed with arms projecting downward from top, an acid.- vessel set inverted in a socket in the top and held between the arms, and a spring pressing it down on a seat carried on the upper end of a weighted swinging lever pivoted on a spindle passing through the arms, all as herein described, and for the purposes set forth.
